• Reverts to [email protected] from nunjucks alias to @11ty/[email protected] (https://github.com/11ty/nunjucks/releases/tag/v3.3.0) to fix regressions when using eleventyConfig.setLibrary to modify the Nunjucks engine internally #4413. This change originally added to fix a now withdrawn audit #4397 and is no longer necessary.

Milestone: https://github.com/11ty/buildawesome/milestone/54?closed=1
Full Changelog: v3.1.7...v3.1.8

• Upgrades liquidjs dependency from 10.27 to 10.30.
• Fixes braces npm audit #4397 also fixed in Dev Server v2.1.2 11ty/dev-server#160
  • This involves some internal chokidar fixes (used by --serve or --watch). If you see EMFILE errors on very large projects please file issues!
• Internals: aliases dependencies for nunjucks to @11ty/[email protected] (see 11ty/nunjucks#27) and gray-matter to @11ty/[email protected]. Application code that uses nunjucks or gray-matter will continue to work as expected.

• Risky, albeit not a breaking change Nunjucks users please take extra care when upgrading to this version. We implemented a somewhat large refactor to our Nunjucks fork. Using new fully-async compatible Nunjucks prerelease v4.0.0-alpha.3. No longer necessary to use async specific tags for {% set %} or {% for %}. You can now use macros with async child content. Fixes #4305 #3788 (and so many other issues!)

Full Changelog: v4.0.0-alpha.7...v4.0.0-alpha.8

• Breaking (canary): bump Node minimum to 22.15+ (previously #3886 20.19+ in v4.0.0-alpha.1) #4271
• Breaking (canary): removes page.inputPathDir and page.dir (introduced in v4.0.0-alpha.5) follow along at #3794
• Feature: Batched Incremental: Fixes #4274 Adds support for multiple eligible incremental files in a single build #4275
• Adds @awesome.me/buildawesome publish and the Build Awesome rename stuff (no breaking changes), more at #4294
  • The biggest risk point here is the addition of generic file name suffixes for Directory/Template Data (e.g. .data.js paired with .11tydata.js) and JavaScript Templates (e.g. .server.js paired with .11ty.js). You may need to review your project to see if you are using these suffixes in pre-existing files.
• Using npm stage publish for extra release security hardening.
• Removes Promise.withResolvers polyfill (no longer necessary) #4289
• Fix preprocessor callbacks run twice when using --incremental #4292
• Upstream repo moved from https://github.com/11ty/eleventy to https://github.com/11ty/buildawesome
• Fix TypeScript data files not being processed by @cypressSap #4247
• Adds TypeScript types d.ts file for Configuration API (documentation pending, see @11ty/eleventy/UserConfig or @awesome.me/buildawesome/UserConfig export)
• Adds Node 26 to CI
• Fix module.register() deprecation message #4283

Add the Build Awesome dependency.

npm install @awesome.me/buildawesome@alpha --save-exact

Now change any npx @11ty/eleventy commands to use npx @awesome.me/buildawesome instead. You can optionally uninstall @11ty/eleventy (recommended for dependency simplification) but it won’t cause issues to have them both installed.
